ABSTRACT:
A string pulling device for a racket stringer includes a base, a rotation unit, a drive unit, a string pulling unit, and a top cover. Thus, the rack of the drive unit meshes with the gear of the rotation unit, so that the rotation disk is rotated rapidly to reach the destined tension unit, thereby facilitating a user adjusting the values of the pulling stress so as to control the pond and tension required for stretching the strings of a tennis or badminton racket. In addition, the string pulling device provides a precise positioning structure.
